It’s no wonder how this San Francisco guitar and drum duo got their name. Whether performing on street corners, festival grounds, or on stage – as they did last Thursday night at Cafe Du Nord – spectators can testify for the band’s monstrous sounds. Lead vocalist and guitarist, Francisco Fernandez, howls gruff harmonies while his accelerated guitar strumming sends drummer, Daniel Aguilar, bouncing up and down in his seat who remarkably keeps up, bashing a pair of brushes against his drum set. Together, their rockabilly aura has conquered any environment they’ve been thrown into, including SXSW, and they will be returning to Austin for a couple of shows this week. Despite the national attention the two have acquired, the band will be back soon to reverberate favorites from their LP, Juices, pressed by Record Pressing. Francisco told the Cafe Du Nord crowd, “Who knows, we might sneak into the Treasure Island Festival.”
